Having a valid email address that aligns with the organization's domain serves multiple purposes: it verifies the identity of the user, enhances communication within the organization, and prevents external or unauthorized users from gaining access. Furthermore, it allows the organization to manage user accounts effectively and maintain a cohesive digital environment for its members.

Invitation emails, age requirements, and administrator approval are more aligned with controlled access and verifications, rather than the initial self-enrollment process. Thus, having a valid email address remains the key condition for members to independently create their accounts.
